HERBERT F. nonmsorvINoNNEs, iNnIANA A ADJUSTABLE LIGHT vApplication ledJuly 9,

This invention relates'to an adjustable light and more particularly to alight'adapted for use ina j arage when inspecting or repairingautomoiles. Y 5 One object of the invention is to provide a lightincluding a standard and a light carrying rod so connected with thestandard that it maybe adjusted vertically and circumferentially uponthe standard and also` Another object of the invention is to Vproy videan adjustable light so constructed that it may be used to illuminate theengine hood or the rod extended beneath the automobile and thetransmission or other elements beneath the chassis.

Another object of the invention is to provide a device of this characterwhich is very simple in construction and strongand durable and capableof withstandingV rough usage without being damaged. l

The invention is illustrated in the accompanying drawing, wherein Figurel is a perspective view of the improved light,

Fig. 2 is an enlarged sectional view illustrating the manner inwhich'the lamp carry- 'ing rod is adjustably connected with thestandard, j A

Fig. 3 is a view showing a portion of the standard in elevation and thelight carrying rod and its securing clamp in section,

Fig. 4: is a bottom plan view of the standard illustrating the manner`in whichl its base is formed, and

Fig. 5 is aview showing the lower portion of the standard partially inside elevation and partially in section. v

light may be a solid bar or consist of a pipe of the desired length. Thelower end of the standard is threaded for engagement in a neck 2 risingfrom a disk 3 forming part of the base ofthe standard. A shank 4t whichis The standard l of the improved adjustable j 1930. serial 1510.466561.

externally threaded extends downwardly from the base or disk 3 directlybeneathy the standard and this shank `carries a clamping l j disk :5zand. securing nut 6. VVThe nut is threaded upon the 'shank and whenltightened 55 Y' forces the disk y5 upwardly so that strips 7 will befirmly clamped between the disk 5 and l the disk 8. From an inspectionyof Figuresk 4l and 5, it will be seen that the strips 7 exi tend acrossthe lower, face of the disk'or base4 60 3 and are arranged in pairsdisposed at right angles to each other. The strips` of each pairy aredisposed at opposite sides of the shank 4 s Y and the Iunder face ofthedisk or base is recessed to form seats 4v8 tofreceive the strips 65 Aandlugs 9 which bear against outer side edges of the strips. ArcuatenotcheslOare formed in the inner edges ofthe strips to receive portionsof the shank and, therefore, when the strips are'set .in placewith theirouter side 70 'edges bearing against the lugs 9 and the shank engaged intheirrecesses 10 they will be firmly' held against longitudinalortransverse movement andwhen the disk 5 is applied to. the shank` andthe nut 6 tightened 75 Y the strips will be rinlybound lbetween the'Vdisks 3 and 5g The end. portions of the strips lare bent downwardlytoform legs 11 which arepof such length that the ends of all the stripsrest upon the groundl or floor and cause 80 the standard ,to be wellsupported in a vertical4 osition. 'n l A f e lightcarrying rod l2 iso-f'a tubular l format-ion in orderv that power Wires 13 may be passedthrough it for engagement with"v 85 contacts ofl a 'socket 14 mountedvatrthe end of aside arm l''formed bybending one end of the rodtransversely. Since the socket is'carried by an arm extendingvtransversely from thev rod, the bulb4v 16 engagedin 'the 90 socket willproject transversely from the rod andwmay be-adjusted circumferentiallyof .f the rod by grasping theV handle 17 at lthe other end of the rodand turning'the rod.

A main or primary clamp 18 and an auX- 95,-V

iliary or secondary clamp 19 are employed to adjustably connect therod12 with'the standard 1. The mainfclamp consists Vof'a strip of resilientmetal Vbent intermediate its j length to form'jaws20 between Vwhich the',100 i standard is to .be gripped andthe Jfree ends a rigid secondaryclamphaving an opening Y of these jaws are bent toward each other, asshown at 21. in Figure 2, to form terminal lips which engage about thestandard.` A bolt 22 extendsthrough the auxiliary clamp and jawsof themain clamp with'its'head 23 Y l bearing against the .outer face of theauxiliary clamp and the 'threaded'.endof this bolt 'Y Ycarries a nut 24having a handle 25 by means of which the nut may be easily rotated in`order to draw the auxiliary clamp andjaws of the'main clamp into tightbindingengagement' with the standard and lamp carrying rod. Theauxiliary clamp consistsof a. strip of strong metal having vone endbentto form a iiange26` to bear against one jaw of the main. clamp and itsother end bent Vto form a shorter ange 27 to engage about the rod 12without contacting with )the main clamp.

this arrangement the auxiliary clamp `may beldrawn into tightbindingengagementwith therein to register with the openings 1n the jaws of theprimary clamp and provided with spaced inwardly extending flanges ofdiffer` ent lengths, one of which-bears against the other of. said rodunits, a'single Vclamping bolt vextending:through Vthe openings in theprimary and secondary clamps Yand' bearing against both rod units, saidbolt being provided at one end with an enlarged head bear-V ingagainstlthe-outer7face of the secondary Y clamp and having its.'k otherend threaded, and

a clamping nut'engaging the threaded end i of the bolt for clamping oneof said rod units ldirectly againsttheadjacent face of the yprimaryclamp and the other rodunitjbetween Vthe Vterminalv lipsof said'primaryjclamp ,i
